ABSTRACT:
An apparatus for filtering industrial process liquids is disclosed herein. The apparatus includes a tank, a continuous conveyor screen mounted within the tank, a partition spanning the tank walls and having an elongated aperture therethrough, and media sealing means upon and surrounding the aperture. One side of the conveyor screen overlies the tank and is guidably retained for sealing engagment with the sealing means, and the other side of the conveyor screen operatively engages a continuous sheet of filter media. The conveyor screen and filter media span the aperture providing upon the underside of the partition an enclosed filtered liquid reservoir and upon its other side an open unfiltered reservoir. An elongated open-top vacuum chamber is supported within the filtered liquid reservoir with its peripheral edge in sealing registry with the conveyor screen and having a first outlet for delivering filtered liquid to a process area. The vacuum chamber also includes a second outlet communicating with the filtered liquid reservoir having a normally closed vacuum release valve. When the media becomes blocked with debris, the vacuum release valve opens and the conveyor screen is advanced to replace the media. The filtered liquid reservoir is provided with an auxiliary outlet for continuously removing contaminated liquid due to seal leakage, and to effect an outward flow from the vacuum chamber for preventing liquid seepage into the vacuum chamber during media replacement.
